The C34, C36, and C38 dienoic omega-lactones were isolated from sebum of the horse (Equus caballus) and the double bond positions were determined by stepwise chemical dissection and analysis of the fragments. The structures found could be formed by delta 9-desaturation at the C18-stage of fatty acid biosynthesis followed by a second delta 9-desaturation when the chains reached C24, C26, C28, C30, or C32 and then addition of one to seven 2-carbon units. These findings provide insight into the dimensions and organization of the endoplasmic reticulum in cells of the sebaceous glands.
从马（Equus caballus）的皮脂中分离出C34、C36和C38二烯型ω-内酯，并通过逐步化学剖析和片段分析确定双键位置。所发现的结构可能是由脂肪酸生物合成的C18阶段的Δ9去饱和作用形成，随后当碳链达到C24、C26、C28、C30或C32时进行第二次Δ9去饱和作用，然后添加一至七个2碳单位。这些发现为皮脂腺细胞内质网的尺寸和组织提供了见解。
